Hey Xcrispi, the Cool bloom is a bit strong and I would go with the 1/8 to start or approx 1g to 1.5 gram if you have a digetal scale and you may want to cutt back a bit on your main bloom in the process.
Hope that helps and I also have to keep the clutter down in my room because of disability, but it still turns into a jungle at times.
Adieu
